What is the process called when a whiptail lizard readily sheds its tail when threatened?

Answer

Autotomy

The startling active defense mechanism employed by whiptail lizards when they are seized or threatened by a predator involves the ability to shed their tail. This process of self-amputation is specifically known as autotomy. Following separation, the detached tail segment continues to move vigorously, serving the crucial function of diverting the predator's attention away from the lizard body, which then uses the distraction to escape into cover.
